QUESTION
I am using Mellanox Technologies MT27800 Family [ConnectX-5], using dpdk multi rx queue with rss "ETH_RSS_IP | ETH_RSS_UDP | ETH_RSS_TCP"
I receive packet with ETH:IP:GRE:ETH:IP:UDP
I want the load balancing to be according to inner ip+port and not with the gre ip
I tried adding ETH_RSS_LEVEL_INNERMOST to the rss_hf but i got an error about rss invalid value 0x800000003afbc should be 0xf00000000003afbc
I am using dpdk 21.11.0 - Is it possible to do it and how? If not how can i do it.
Is it also supported in dpdk 19.11?
...ANSWER
Answered 2022-Mar-12 at 16:36Support for GRE and/or Inner RSS is touch and go for many NIC, so most NIC does not work out of box. For example
- For Intel Fortville (10gbps, 25Gbps, 40Gbps) NIC: one needs to update firmware and DDP profile to parse and compute inner RSS.
- For Intel Columbiaville (100Gbps, 50Gbps, 25Gbps) NIC: one needs to update firmware and then update driver. As I recollect default DDP profile parses GRE.
- In case of Mellanox MLX5 (there are multiple variant for ConnectX-5 and Connect-6), some of them support GRE based parsing and RSS, while other require ESWITCH to perform such actions.
Hence using testpmd one needs to
- enable MQ_RSS in port and RX queue configuration
- For specific (inner RSS) enable via RTE_FLOW API
With MT2892 Family [ConnectX-6 Dx]
one can enable Inner 5 tuple RSS for GRE encapsulated packet with testpmd.
- Start packet generator (DPDK pktgen) use
sudo ./usr/local/bin/pktgen --file-prefix=3 -a81:00.0,txq_inline_mpw=128 -l 6-27 -- -P -m "[8-11:12-27].0" -N -s"0:rtp_balanced_gre.pcap"
- Start testpmd in interactive mode with multiple RX queues using
dpdk-testpmd --socket-mem=1024 --file-prefix=2 -l 7,8-23 -a0000:41:00.1,mprq_en=1,rxqs_min_mprq=1,mprq_log_stride_num=9,txq_inline_mpw=128,rxq_pkt_pad_en=1,rxq_cqe_comp_en=4 -- --port-numa-config=0,0 --socket-num=0 --burst=128 --txd=8192 --rxd=8192 --mbcache=512 --rxq=16 --txq=16 --nb-cores=8 -a --forward-mode=io --numa --rss-udp --enable-rx-cksum --no-mlockall --no-lsc-interrupt -a --enable-rx-cksum --enable-drop-en --eth-link-speed=100000 --no-rmv-interrupt -i
- In interactive shell configure the rule as
flow create 0 ingress pattern eth / ipv4 / gre / eth / ipv4 / udp / end actions rss level 2 types ip udp end queues 0 1 2 3 end / end
.
Note:
- Ensure to use the right format in match field eth / ipv4 / gre / eth / ipv4 / udp /
- if the rule is not set on the device only device RX queue0 will be receiving the packets.

I'm struggling with this nested document too much. I tried to read the document and also follow other SO responses to see if it works for me, but I'm not getting the results that I'm looking for. I want to extract some information from a big nested document.

Answered 2020-Oct-08 at 23:51You can do (almost!) anything with an aggregate query. In your case I suggest using $unwind
to convert the lists to onjects, then $match
on your target field(s), $project
to trim down the output, $replaceRoot
to simplify the structure and $limit
for good measure as there's actually 2 records that match your criteria.
